I've got rust here that's been spinning for ~12 years in my basement,
24x7, and I expect it to spin for a while longer.
I can't quite come to terms with the idea of storage with a suicide
clock, ticking away.
It's likely that, sometime in the next year, I wll be replacing that
hardware, but if that happens, the hardware will retire on my schedule,
instead of losing its own blue smoke, by itself.
All hardware fails eventually, and in that sense all hardware has a
suicide clock, as you put it. However, I have been using one of the
early model SSDs for almost ten years now, and I will probably continue
to use it for a good while yet. As for the drive I mentioned earlier, a
TBW rating of 100 TB is, in practical perspective, very high.
Since we were talking about the effects of swap, let's say you have a
four GB swap partition or file on your SSD with a TBW rating of 100 TB.
Let's come up with a pretty extreme example and say your computer swaps
a ton and writes that partition full, twice every day. Assuming writes
to other partitions are relatively normal, say around four gigabytes per
day on average, this gives the drive an expected lifespan of about two
decades by my count. Given that, I really would not worry about putting
swap on an SSD. In consumer-grade hardware under normal use, I would
expect the electronics to rot before the TBW comes up.
